PAPER CUTTER /4 E 1 M 6 l6 y In venior A ftorneys Patented Sept. 10,1940 UNITED STATES PATENT OFFICE PAPER CUTTER 2 Claims.

This invention appertains to new and useful improvements in paper driersand more particularly to a cutter mechanism for employment therewith.

The principal object of the present invention is to provide a cuttermechanism for use in conjunction with paper driers whereby the cuttercan be quickly operated to sever the paper in the event of a jam-up inthe drier.

Another important object of the invention is to provide a cutter of thecharacter stated which can be quick-acting and not susceptible to theready development of defects.

These and various other important objects and advantages of theinvention will become apparent to the reader of the followingspecification.

In the drawings:

Figure 1 represents a fragmentary vertical sectional view through agroup of drier cans showing in section the cutting mechanism.

Figure 2 is a side elevational view of the cutter disk and guardtherefor.

Figure 3 is a cross sectional view of one of the cutter assemblies.

Figure 4 is a sectional view through one of the guards.

Figure 5 is a longitudinal sectional view fragmentarily through one ofthe cutter assemblies.

Figure 6 is a vertical sectional view taken substantially on the line6-6 of Figure 1.

Figure 7 is a perspective view of one of the drawbars.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 represents the drying rolls of the upperflight, while numeral 6 denotes the rolls of the lower flight, theserolls 5 and 6 being in horizontal offset relation.

A cutter assembly generally referred to by numeral 1 is preferablymounted on the frame over each of the lower rolls 6 and each ofthesecutter assemblies consists of an elongated tube 8 having the squarepassageway 9 extending longitudinally therein. The side of the tube 8 isformed with a longitudinally extending slot l through which projects thebushing II from the shell of the motor I2, which motor is located on aslide plate 13 capable of sliding on the bottom of the passageway 9. Anear l4 extends laterally from the motor l2 and to this is pivotallyconnected as at I5, the drawbar IS.

The armature shaft I! of the motor l2 extends through the bushing H andis threaded at its outer end. This threaded outer end projects throughthe cutter disk l8 and nuts I9 on this threaded portion of the armatureshaft fixes the location of the cutter disk l8 on the armature shaft.

A semi-circular shaped grill 20 serves as a guard for the upper portionof the disk l8, this guard having hub members 2| and 22. The hub member2| has the outer end of the armature shaft journaled therein, while thehub member 22 fits over the outer end of the bushing II and ispreferably keyed or pinned thereto.

Leg members 23 extend downwardly from the ends of the tube 8 and areattached or secured in some suitable manner to the drier frame 24.

Obviously when the paper strip 25 buckles or jams in the drier, the samecan .be readily severed by sliding the motor l2 longitudinally in theadjacent tube 8 with the motor operating the cutter blade 18.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous ehanges in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. A web cutter comprising an elongated stationarily mounted tube havinga slot extending longitudinally in the side thereof, a motor slidablelongitudinally in the tube and having an armature shaft protrudingthrough the slot, and a cutter carried by the outer end of the armatureshaft, and an elongated rod extending into the tube and pivotallyattached to the motor and adapted to move the motor longitudinally inthe said tube.

2. A web cutter of the character described comprising an elongatedstationarily mounted tube having a slot extending longitudinally in theside thereof, a motor slidably disposed in the tube, means for movingthe motor longitudinally in the tube, a bushing projecting from themotor and through the slot, said motor including an armature shaftprojecting through the bushing and beyond the outer end thereof, a knifecarried by the outer end of the armature shaft, and a guard partlyencompassing the knife and having one side thereof secured to the outer50 end of the bushing.
